The growth of data centers, from large CPDs to microdatacenters, demands increasingly precise and efficient cooling solutions. Meeting standards such as ASHRAE TC 9.9, Uptime Institute TIER I–IV availability levels, and efficiency indicators like PUE (ISO 30134-2) is essential to ensure operational continuity and optimize energy costs.
Split-type air conditioners have become obsolete in this context, as they lack the ability to maintain stable temperature and humidity control, redundancy, and fault detection. In contrast, precision air systems with Scroll compressors and, more importantly, Inverter technology, have become the most reliable option.
Scroll vs. Inverter: Technical Comparison
Scroll (On/Off): lower initial cost, suitable for stable thermal loads, but with lower efficiency and shorter lifespan.
Inverter: continuous modulation, higher energy efficiency, temperature precision of ±0.5–1 °C, reduced consumption, and lifespan of up to 15 years.
Application in Data Centers
Depending on size and load profile:
Small (1–3 racks): Inverter.
Medium (4–15 racks): Inverter with high precision.
Large (15+ racks): Inverter combined with advanced systems (free cooling, hot aisle).
A success story in Bolivia, led by Amper Group with the support of Atlantic Power, demonstrated that migrating from Scroll to Inverter compressors enabled immediate energy savings of up to 12%, extended equipment lifespan, and prevented critical server failures.
Conclusion
Implementing Inverter compressors not only improves energy consumption but also ensures regulatory compliance, equipment availability, and data center sustainability. For organizations seeking efficiency and reliability, this is the ideal technological solution.
